Q.  Which of the following factors are responsible for Typhoon Formation and Development?

1. Warm sea surface temperatures
2. Cold sea surface temperature
3. High humidity in the lower to middle levels of the troposphere

a. 1,3,4,5,6
b. 2,3,4,5,6
c. 1,3,4,5,7
d. All

ANSWER: 1,3,4,5,6
 
There are six main requirements for typhoon formation and development and they are:
1. Sufficiently warm sea surface temperatures
2. Atmospheric instability
3. High humidity in the lower to middle levels of the troposphere
4. Enough Coriolis force to develop a low pressure center
5. A pre-existing low level focus or disturbance
6. Low vertical wind shear
